Specification of Letters Patent.

' Patented Jan. 7, 1913.

To all whom it may concern:

Be it known that I, AUGUSTUS R. LAMP- LUGH, a citizen of the UnitedStates, residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, haveinvented a new and useful Improvementin Go-Carts, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, which form a part of thisspecification.

The object of the invention is to provide, between the axles and thevehicle body, an arrangement of spring-supports, combining the maximumof strength and elasticity, by means of which the body may be freelyrocked both in a longitudinal and transverse direction as well as up anddown.

The invention consists of sets of side Springs and end springs,superposed one upon another, and supported from the axle and supportingthe body, whereby the above objects are attained, as more particularlyhereinafter described and pointed out in the claims.

In the drawings: Fig. 2 an end view; spective view.

a are the axles and b the wheels; Connecting the axles, at each side ofthe vehicle, is a spring 0. The central part ofthe spring 0 issubstantially horizontal and located above the level of the axles, whilethe ends Figure l is a side view and Fig. 3 a detail perconnecting withthe axles are of compound curve form. The extremities overlie the axleand are secured thereto by means of clips (Z riveted to the springs andaxles. Overlying each spring 0 is a spring 6. The central part of thespring 6 extends in a substantially horizontal direction and is rivetedto the spring 0. Eachend of the spring 6 is curved upward and thencedownward, and extends substantially beyond the corresponding axle. Theextremity is bent about '45' a pin 7 extending between the-"uprightflanges of a holder 9. Secured to the bottom of the holder g is a holderh, bet-ween the depending flanges of which is a pin 2'. At each end ofthe vehicle a spring is connects the holders It on opposite sides of thevehicle, the'extremities of the springs being bent around the pins a ofSaid holders. The spring is is bow-shaped with its convex side facingupward. Overlying each spring is is a spring we. The central part of thespring m is riveted to the central part of the spring is. The ends ofthe spring we extend upward and thence outward toward the side of thevehicle. Secured to the ends of each spring we are longitudinally-extending springs a. Each spring a is secured at one extremity to thecorresponding extremity of the spring: 172, and thence is reverselycurved upwardly and thence horizontally, the horizontally-extending endbeing secured to the vehicle body 0.

p is the handle the side arms of which are supported on brackets r onthe rear axle, while their forward extremities are riveted to thecentral parts of the springs c' and 6.

By means of the construction described, the vehicle-body may be movedfreely upand-down as well as rocked in either a horizontal or atransverse direction. The construction is such that the cushioningeffect is well distributed, and the springs may be made quite strongwhile preserving the desired degreeof elasticity.

WVhile I have applied the term springs to all the constituent elementsof the gear connecting the axles and vehicle body, it is obvious thatall of them need not have a substantial spring action. 7

Having now fully described my invention, what I claim and desire to'ters Patent is 1; In a go-cart, the combination with the axles andvehicle body, of lower longitudinally-extending side-springs connectingthe axles, upper longitudinally-extending side-springs overlying andconnected to the lower side-springs and extending substan tially beyondthe axles at opposite ends, lower transversely extending end-springsconnecting the extremities of the upper sidesprings, uppertransversely-extending endsprings overlying and connected to the lowerend springs, and longitudinally extending springs connecting the uppertransversely-extending end-springs with the vehicle body.

2. In a go-cart, the combination with the axles and vehicle body, of apair of longitudinally extending side springs extending beyond theaxles, means by which said springs are supported between their ends fromthe axles, a pair of transverse end springs, means by which said endsprings are supported between their ends from the ends of said sidesprings, and springs connecting the ends of said end springs with thebody.

protect by Let- 3. In a go-cart, the combination with the axles and thevehicle body, of a pair of lower longitudinally-extending side-springseach of which has a central horizontal portion above the level of theaxles and curved end portions connected to the axles,-a pair of upperlongitudinally-extending side-springs each of which has a centralhorizontal portion secured to the central horizontal portion of thecorresponding lower side-spring and end portions curved successivelyupward and downward and extending substantially beyond the axles, a pairof transversely-extending lower end springs each of which is connectedat opposite ends to the corresponding ends of the pair of upperside-springs and is curved upward'between its ends, a pair oftransversely-extending upper end springs each of which has a centralportion connected to the corresponding lower end-spring andnpwardlyextending end portions, and two pairs of longitudinally-extending endsprings, each pair being secured to opposite ends of the correspondingupper-end spring and thence curvedupward and connected to the body.

In testimony of which invention, I have hereunto set my hand, atPhiladelphia, on this 9th day of November, 1911.

AUGUSTUS R. LAMPLUGH.
